### SUMMARY Following the Ant Design version upgrade, the Table component's advanced header/column features (sticky headers, column resize/measure logic, etc.) trigger heavy internal operations that get re-run on every re-render, and resizing the browser window (or a dashboard tile) forces TimeTable's underlying TableView/TableCollection (react-table + antd Table) to re-render on every resize tick — combining into visible jank while dragging, especially for tables with many rows/columns. This adds a window resize listener in TimeTable.tsx: as soon as a resize event fires, TableView is unmounted from the render tree (isSizeStable flips to false); once no further resize events arrive for 500ms (RESIZE_DEBOUNCE_MS), it's rendered again. The listener is attached once on mount and cleaned up (listener + pending timer) on unmount. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF Before: https://github.com/user-attachments/assets/c029a17a-af9f-4cea-aff4-f4722f3ac0ec After: https://github.com/user-attachments/assets/99a632c1-1e28-4829-aa99-0fec97a5a2ac ### TESTING INSTRUCTIONS - Add a Time-series Table chart with many metrics/columns to a dashboard. - Drag the browser window edge to resize it continuously. - Confirm the table content disappears while actively resizing and reappears ~500ms after resizing stops, with no console errors. - TimeTable.test.tsx unit tests continue to pass. ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
